The present invention relates to a performance reproducing system such as a so-called karaoke performance reproducing system for business, which enables selection selection operation by an input currency.

The present invention is a performance reproducing system that enables selection and selection of arbitrary songs from a plurality of plays recorded on a recording medium in accordance with a currency to be inputted. The improved song operation is performed within a predetermined time at the start of reproduction of the selected songs. In this way, the playback operation of the unnecessary song is stopped to perform the playback operation of the newly selected desired song.

Background Art [0002] Conventionally, as a performance reproducing system that receives a music selection operation in accordance with an input currency and plays it, for example, a commercial karaoke performance reproduction which reproduces an orchestra performance (so-called karaoke performance) without a singer recorded on a recording medium such as a magnetic tape or an optical disc. The system is known.

In general, the karaoke performance reproducing system for commercial use detects that a predetermined amount of money has been input, accepts a music selection operation, a performance start operation, and the like and reproduces a designated song on a recording medium. The above-described music selection operation has been conventionally employed in which a plurality of pieces of music are designated in advance, or a method of designating one song one by one each time playback.

However, in the conventional karaoke performance reproducing system, when the music piece is changed by actually listening to the re-selection operation after the start of the performance, that is, the beginning of the selected song, the music selection operation is not accepted or is performed in advance. In the case where a minute's currency has been put in, the performance of the song is ended and the re-selection operation is accepted for the remaining number of songs, and there is a problem that the user has to pay a fee for the song that the user does not want.

Accordingly, the present invention has been made in view of the above-described conventional problems, and provides a performance reproducing system having a novel configuration in which a reselection operation is accepted within a predetermined time at the reproduction start point of the selected song.

In order to solve the problems as described above, the present invention provides a performance reproducing system in which a music selection operation can be performed on an arbitrary song from a plurality of songs recorded on a recording medium according to an input currency. And a logic circuit means for validating the operation when the reselection operation is performed within a predetermined time set in the timer operated by the signal indicating the setting start point in the timer operated by the signal indicating the viewpoint. Doing.

As shown in the figure, a money inlet 31, an operation state display unit 32, and the like are provided. Thus, as shown in FIG. 1, the coin box 30 is provided with a currency detector 33, in which a predetermined amount of money (e.g., 100 won coin) is inserted into the coin inlet. Each time it detects that it has been put into 31, an addition pulse is supplied from the money detector 33 to the first counter 34.

The above-mentioned first counter 34 is for setting a fee, and a rate change switch 34A and a song change switch 34B are connected, and a predetermined rate (for example, set by the rate change switch 34A). , 200 won or 300 won) into the money inlet 31, adds a pulse added by a predetermined song (e.g., one or two songs) set by the song change switch 34B. Supply to the third counters 35 and 36.

Reversible counters are used for the second and third counters 35 and 36, respectively. The second counter 35 is a timer 37 which is operated by the timer operation signal from the playing section 18 of the CD player body 10 described above. The subtraction pulse is supplied at the start of the performance of the tune selected by the user, and the subtraction pulse and the addition pulse supplied from the first counter 34 are counted, and while the count result is one or more, the operation unit ( The music selection permission signal for allowing the music selection operation by 17) is supplied to the motion control logic circuit 38 at the same time as the supply term to the music selection possible display section 32A of the display section 32. The third counter 36 is supplied with a falling edge pulse of the timer output of the timer 37 as a subtracted pulse through the first differential circuit 39, and the subtracted pulse and the add pulse.
